Seismic Analysis of a Low-Rise Base-Isolated Structural System
A base-isolation system was developed for earthquake protection of low-rise structures. The system incorporates spherical supports for the base, a specially designed spring-cam system to keep the base supported under normal conditions, and moves for the duration of the earthquake under the constraint of a spring with optimized stiffness characteristics. The dynamic behaviour of a three-story co...
متن کاملThe Stochastic Response of Asymmetric Base Isolated Buildings
The coupled lateral–torsional stochastic response of an asymmetric one-storey base isolated building to earthquake excitation is presented. The stochastic model of the 1940 El-Centro earthquake, which preserves the non-stationary evolution of the amplitude and frequency content of the ground acceleration, is used as earthquake excitation. The base isolator consists of an array of elastomeric be...
متن کاملResponse of high-rise and base-isolated buildings to a hypothetical mw 7.0 blind thrust earthquake.
High-rise flexible-frame buildings are commonly considered to be resistant to shaking from the largest earthquakes. In addition, base isolation has become increasingly popular for critical buildings that should still function after an earthquake. How will these two types of buildings perform if a large earthquake occurs beneath a metropolitan area? To answer this question, we simulated the near...
متن کاملDynamic Response of High-Rise Buildings to Stochastic Wind Loads
This paper presents results of a recent study addressing issues concerning the dynamic response of high-rise buildings. Utilizing a high-frequency base-balance, the alon~w;:~d, acrosswind and torsional components of aerodynamic loads and their statistical corm!ations for a wide range of generic building shapes of different aspect ratios in two approach flow conditions are quantified. A random-v...
متن کاملSimplified Method for the Seismic Design of Low-Rise, Shear Wall Base- Isolated Buildings
A simplified method for the seismic design of low-rise, base-isolated shear wall structures is proposed in MOC-2012. This simplified method is basically a hybrid method, where the design of the isolation system is a simpler version for the static method available in US guidelines for the design of base-isolated structures and the design of the superstructure essentially is an improved version o...
